Cannot upgrade phones online with a Mobile Share Value Plan

Cannot upgrade phones online with a Mobile Share Value Plan

I just upgraded to a Mobile Share Value plan a couple of days ago, I even called to make sure that I could upgrade my phones after moving to the plan, but on Christmas I tried to upgrade my phone online and found myself smacking into a wall stating that I could not upgrade online and to call. I expected that since I couldn't upgrade online I could get the same phones and prices by calling by phone. I was wrong. I would have never switched to the plan before upgrading if I had known this would happen.
